The SkewTolerance property is used for the detection of barcodes in skewed documents, but it can have a negative impact on the performance of the ScanBarCode command, especially when reading PDf-417 and Datamatrix barcodes. One solution to this problem is to use xml settings, which allow you to store sets of properties which are applied successively until a barcode is decoded.<\/p>\n
For example, if you create a an xml file containing…<\/p>\n
<xml version=’1.0′ encoding=’iso-8859-1′>
\n<SoftekBarcode>
\n<Properties>
\n<ReadCode39>1<\/ReadCode39>
\n<ReadCode25>1<\/ReadCode25>
\n<ReadPDF417>1<\/ReadPDF417>
\n<ReadDataMatrix>1<\/ReadDataMatrix>
\n<MultipleRead>1<\/MultipleRead>
\n<ReadCode128>1<\/ReadCode128>
\n<ScanDirection>15<\/ScanDirection>
\n<MinLength>4<\/MinLength>
\n<MaxLength>999<\/MaxLength>
\n<ShowCheckDigit>1<\/ShowCheckDigit>
\n<SkewTolerance>0<\/SkewTolerance>
\n<\/Properties>
\n<Properties>
\n<SkewTolerance>5<\/SkewTolerance>
\n<\/Properties>
\n<\/SoftekBarcode>
\n<\/xml><\/p>\n
…and in your code replace the lines where you set the properties of the toolkit with one line:<\/p>\n
barcode.LoadXMLSettings(“settings.xml”)<\/p>\n
Then, when you call ScanBarCode, the toolkit will first apply tthe settings in the first section of the xml file and only set SkewTolerance to 5 if it wasn’t able to read a barcode in the normal orientations.<\/p>\n","protected":false},"excerpt":{"rendered":"
